Box Assembly with Safeguard Locking Function

ABSTRACT

A box assembly includes a main body and a cap mounted on the main body. The main body is formed with a receiving space and an opening connected to the receiving space. The main body is provided with a plurality of first locking structures located adjacent to the opening. The cap includes a covering plate and a mounting member extending sideward from the covering plate. The mounting member of the cap is inserted into the opening of the main body. The mounting member of the cap is provided with a plurality of second locking structures releasably locked with the first locking structures of the main body.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a storage device and, more particularly, to a box (or bottle) assembly for storing articles, such as medicines or the like.

2. Description of the Related Art

A conventional medicine box (or bottle) comprises a main body containing medicine therein, and a cap pivotally connected with the main body. Thus, when the cap is mounted on the main body, the medicine box is closed, and when the cap is removed from the main body, the medicine box is opened. However, the cap is not locked onto the main body exactly, such that the cap is easily detached from the main body. Thus, the medicine box will be opened inadvertently, such that the medicine easily drops from the medicine box and will be contaminated. In addition, the child easily opens the medicine box and eats the medicine in the main body, thereby causing danger to the child.

BRIEF SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a box assembly with a tenon-mortise structure to provide a safeguard locking function.

In accordance with the present invention, there is provided a box assembly comprising a main body and a cap mounted on the main body. The main body is formed with a receiving space and an opening connected to the receiving space. The main body is provided with a plurality of first locking structures located adjacent to the opening. The cap includes a covering plate and a mounting member extending sideward from the covering plate. The mounting member of the cap is inserted into the opening of the main body. The mounting member of the cap is provided with a plurality of second locking structures releasably locked with the first locking structures of the main body.

According to the primary advantage of the present invention, the second locking structures of the cap are locked with the first locking structures of the main body, such that the cap is locked onto the main body solidly and steadily, thereby preventing the cap from being removed from the main body inadvertently, and thereby preventing the medicines from falling from the main body.

According to another advantage of the present invention, the second locking structures of the cap are locked with the first locking structures of the main body, such that it is necessary to apply a larger force on the cap so as to remove the cap from the main body, thereby preventing the box assembly from being opened unintentionally, and thereby preventing the medicine in the main body from being eaten by the child.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1-3, a box assembly 1 in accordance with the preferred embodiment of the present invention comprises a main body 10 and a cap 12 mounted on the main body 10.

The main body 10 is formed with a receiving space 100 and an opening 102 connected to the receiving space 100. The main body 10 is provided with a plurality of first locking structures 104 located adjacent to the opening 102. The receiving space 100 of the main body 10 is used to store items, such as medicines or the like.

The cap 12 includes a covering plate 120 and a mounting member 122 extending sideward from the covering plate 120. The mounting member 122 of the cap 12 is inserted into the opening 102 of the main body 10. The mounting member 122 of the cap 12 is provided with a plurality of second locking structures 1220 releasably locked with the first locking structures 104 of the main body 10.

In the preferred embodiment of the present invention, the mounting member 122 of the cap 12 is provided with a plurality of elastic plates 1222 and a plurality of securing pieces (or inserts or plugs) 1224. The second locking structures 1220 of the cap 12 are provided on the elastic plates 1222 respectively. The elastic plates 1222 are arranged between the securing pieces 1224. The securing pieces 1224 of the cap 12 are inserted into the opening 102 of the main body 10.

In the preferred embodiment of the present invention, the mounting member 122 of the cap 12 is provided with a plurality of slits 1226, and each of the slits 1226 is defined between one of the elastic plates 1222 and one of the securing pieces 1224. Thus, the elastic plates 1222 of the cap 12 contract inward by provision of the slits 1226.

In the preferred embodiment of the present invention, each of the first locking structures 104 of the main body 10 is a boss, a projection, a hole, a groove or a cavity. Preferably, each of the first locking structures 104 of the main body 10 is a hole.

In the preferred embodiment of the present invention, each of the second locking structures 1220 of the cap 12 is a boss, a projection, a hole, a groove or a cavity. Preferably, each of the second locking structures 1220 of the cap 12 is a boss.

In operation, referring to FIGS. 2 and 3 with reference to FIG. 1, the second locking structures 1220 of the cap 12 are locked with the first locking structures 104 of the main body 10, such that the cap 12 is locked onto the main body 10. When the user applies a force on the covering plate 120 of the cap 12, to pull the cap 12 outward relative to the main body 10, the second locking structures 1220 of the cap 12 interfere with the first locking structures 104 of the main body 10, such that the elastic plates 1222 of the cap 12 are pressed to gradually contract inward by provision of the slits 1226, until the second locking structures 1220 of the cap 12 are released from the first locking structures 104 of the main body 10. When the second locking structures 1220 of the cap 12 are released from the first locking structures 104 of the main body 10, the cap 12 is detached from the opening 102 of the main body 10 as shown in FIG. 3.

On the contrary, the mounting member 122 of the cap 12 is inserted into the opening 102 of the main body 10, with the second locking structures 1220 of the cap 12 aligning with the first locking structures 104 of the main body 10 as shown in FIG. 2. When the elastic plates 1222 of the cap 12 are inserted into the opening 102 of the main body 10, the second locking structures 1220 of the cap 12 presses the inner wall of the main body 10, such that the elastic plates 1222 of the cap 12 are pressed to contract inward by provision of the slits 1226. When the second locking structures 1220 of the cap 12 align with the first locking structures 104 of the main body 10, the second locking structures 1220 of the cap 12 are moved outward by the restoring force of the elastic plates 1222, and are locked with the first locking structures 104 of the main body 10 as shown in FIG. 1, such that the cap 12 is locked onto the main body 10.

Accordingly, the second locking structures 1220 of the cap 12 are locked with the first locking structures 104 of the main body 10, such that the cap 12 is locked onto the main body 10 solidly and steadily, thereby preventing the cap 12 from being removed from the main body 10 inadvertently, and thereby preventing the medicines from falling from the main body 10. In addition, the second locking structures 1220 of the cap 12 are locked with the first locking structures 104 of the main body 10, such that it is necessary to apply a larger force on the cap 12 so as to remove the cap 12 from the main body 10, thereby preventing the box assembly 1 from being opened unintentionally, and thereby preventing the medicine in the main body 10 from being eaten by the child.
